10. WIRING EXAMPLE
10-1 HOW TO CONNECT WIRINGS
•
Wire only after removing the control box lid as shown in
Fig. 17, refering to view A or B depending on the type of unit.
•
When clamping the wiring, use the included clamp material
(9) and (10) as shown in the Fig.17 to prevent outside pres-
sure being exerted on the wiring connections and clamp
firmly.
•
Be sure to attach power supply wiring and earth wire to the
control box with the clamp.
•
When doing the wiring, make sure the wiring is neat and
does not cause the control box lid to stick up, then close the
cover firmly. When attaching the control box lid, make sure
you do not pinch any wires.
•
Outside the air conditioners, separate the weak wiring (remote
controller and transmission wiring) and strong wiring (earth
wire and power supply wiring) at least 50 mm so that they do
not pass through the same place together. Proximity may
cause electrical interference, malfunctions, and breakage.
[ PRECAUTIONS ]
•
Refer to the “REMOTE CONTROLLER INSTALLATION
MANUAL” on how to install and lay the wiring for the remote
controller.
•
See also the “Wiring Diagram plate” attached to the control
box lid when laying electrical wiring.
•
Connect the remote controller and transmission wiring their
respective terminal blocks.
• Do not, under any circumstances, connect the power sup-
ply wiring to the remote controller or transmission wiring
terminal block. Doing so can destroy the entire system.
[ Connecting electrical wiring, remote controller wiring,
and transmission wiring ] (Refer to Fig. 18)
•
Power supply and Earth wiring
Remove the control box lid.
Next, pull the wires into the unit through the wiring through
hole and connect to the terminal block (3P).
Be sure to put the part of the sheathed vinyl into the control
box.
•
Remote controller and transmission wiring
Pull the wires into the unit through the wiring through hole
and connect to the terminal block (6P).
Be sure to put the part of the sheathed vinyl into the control
box.
Clamp
Clamp
Remove the clasp with screwdriver.
Let a wire go through the clasp, and
be sure to attach the clasp to the
control box.
Clamp
Match up the wiring sheath with the
fixing clasp with the clamping
material for preventing slippage on
the power supply side and clamp
(accessory (9)).

Penetration area
•
Make sure to let a wire go through a wire penetration area.
•
After wiring, seal the wire and wire penetration area to prevent
moisture and small creatures from the outside.
•
Wrap the strong and weak electric lines with the sealing
material (12) as shown in the figure below.
(Otherwise, moisture or small creatures such as insects from
the outside may cause short-circuit inside the control box.)
Attach securely so that there are no gaps.
